A. Controls the aggregate CPU and memory resources of the DRS cluster.B. Allocates available resources among the virtual machines.C. Consolidates workloads to reduce the power consumed by the cluster.D. Provides easy migration and monitoring.

QUESTION 37In what two situations would an administrator use Storage vMotion? (Choose two.)

A. To create new virtual machines in the host.B. To bring powered-down hosts back online.C. To select separate locations for the virtual machine disk files.D. To migrate virtual machines from one datastore to another.

Answer: CDExplanation:You can use vMotion to migrate virtual machines to a different host and datastore simultaneously. In addition, unlike Storage vMotion, which requires a single host to have access to both the source and destination datastore, you can migrate virtual machines across storage accessibility boundaries.http://pubs.vmware.com/vsphere-51/index.jsp?topic=%2Fcom.vmware.vsphere.vcenterhost.doc%2FGUID-561681D9-6511-44DF-B169-F20E6CA94944.html

QUESTION 38How does fault tolerance provide continuous availability?

A. By providing the availability required by most applications running in virtual machines, independent of the operating system and application running in it.B. By using a feature called Changed Block Tracking (CBT), which backs up content.C. By creating and maintaining a secondary virtual machine that is identical to primary machine.D. By using the host as the medium to provide asynchronous replication of datastores.

Answer: CExplanation:VMware Fault Tolerance provides continuous availability for virtual machines by creating and maintaining a Secondary VM that is identical to, and continuously available to replace, the Primary VM in the event of a failover situation.http://pubs.vmware.com/vsphere-4-esx-vcenter/index.jsp?topic=/com.vmware.vsphere.availability.doc_41/c_plan_understand_ft.html

QUESTION 39What can an administrator do if they does not want Storage DRS to perform all storage balancing functions?
